I don't understand this but I will take your word for it. Why don't we fix
it?

Again, same comment.

I think I got that bit but not even sure here. It would be wonderful and I
would think important to do color grading in Blender.

How about adding these monitors to the compositor as node outputs viewers?
It is true that we have a couple of these monitors in the VSE but even
there they are very primitive compared to the shots in the tutorial. There
examples of have R, G, and B channels viewable all at once and then
adjustable is a powerful tool that I would like to have!

Thanks for your time!
